Vapor Chamber Single-Piece Support Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vapor chambers face manufacturing complexity due to multiple independently placed support rods, and insufficient vapor channels lead to reduced cooling performance.
Innovation Solution
A vapor chamber with a single-piece support structure comprising multiple support bodies and ribs, arranged to form hollow portions, simplifies manufacturing and provides sufficient gas channels for improved heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple support rods are independently disposed and fixed by thermal diffusion welding, then the chamber stability is maintained, but the manufacturing process becomes very complicated
Solution Approach 1:
Multiple independent support rods are merged into a single integrated support structure comprising a support plate with multiple support legs. This integration eliminates the need for separate placement and thermal diffusion welding of multiple rods, significantly simplifying the manufacturing process while maintaining chamber stability through the distributed support legs
2Stability of the object's composition
If support rods are placed one by one and fixed by thermal diffusion welding, then the support structure is stable, but the vapor channels become insufficient causing reduced cooling performance
Solution Approach 1:
The support structure is segmented into multiple support legs extending from a support plate, creating numerous hollow portions between the legs. This segmentation provides sufficient vapor channels for working fluid flow while maintaining structural stability, resolving the conflict between structural integrity and heat transfer performance
3Area of stationary object
If multiple support rods are independently disposed, then the manufacturing requires multiple placement steps, but the support coverage is sufficient
Solution Approach 1:
Multiple support functions are merged into a single support plate structure with multiple integrated support legs. This allows the entire support assembly to be manufactured as one piece and installed in a single operation, dramatically improving manufacturing efficiency while maintaining adequate support coverage through the distributed leg arrangement
